- a regular map (graph theory)Regular map (graph theory)In mathematics, a regular map is a symmetric tessellation of a closed surface. More precisely, a regular map is a decomposition of a two-dimensional manifold such as a sphere, torus, or Klein bottle into topological disks, such that every flag can be transformed into any other flag by a symmetry...
